  • Platform/Features/IonMonkey  + (Goals: * Provide a backend that can match
    Goals: * Provide a backend that can match or beat the Trace JIT or Crankshaft in speed. Sub-goals: ** Fine-grained specialization and de-specialization. ** Integration with type inference. * Clean, textbook IR so optimization passes can be separated and pipelined with well-known algorithms. * Document and comment well so the implementation and its side effects can be easily understood. * Recompilation, debugging, bailouts are all related - and should be solved up-front. * First SpiderMonkey JIT that starts off with peer reviews! * (Unknown feasibility) Act as a baseline compiler to replace JM2. * Manage memory much better, in part to avoid range problems on x64. Avoiding these: * Aggressive stores. We should move state syncing to bailout points.

  • Features/Platform/Graphite font shaping  + (Graphite support is targeted primarily at
    Graphite support is targeted primarily at minority-language user communities in South-East Asia and other areas where complex writing systems are used, and industry standards are still a long way from providing adequate support. Examples include minority groups in Myanmar (Burma) using variants of Burmese script[3] and communities in Thailand using the Lanna script.[4] Graphite is also likely to be valuable in implementing scripts such as SignWriting[5], used by some sign-language communities. In addition, Graphite can be used by font designers to provide improved support for complex behaviors such as calligraphic styles and placement of multiple diacritics even in "simple" scripts. [3]

  • Features/HTTP Digest header verification  + (Jim downloads LibreOffice but the file doe
    Jim downloads LibreOffice but the file doesn't seem to work. Jim contacts the LibreOffice support group and they suggest that Jim manually validates the hash. Jim uses Microsoft Windows, so they tell him to download a small program since nothing comes with the OS to do this. Jim installs the program, and after figuring out how to use it & select the file to hash, figures out that the download is corrupt. He contacts LibreOffice support & they tell him to re-download the file again, and manually check it again until the hash is correct. Jim has an unreliable internet connection, so it isn't until his third try that the download completes without errors. Janie downloads VLC and as a technical user, she recognizes the SHA-1 hash on the download page: "If you have a problem, click here. SHA-1 checksum: 65742a2194185790925a4dcd6105ca27eb3e386a" As a seasoned Unix user, she knows she may open a terminal and type a command to manually verify that the download completed without errors. Luckily there are no errors, so she uses the file. Janie wishes her browser automatically took care of this for her, even though she knows how to do it. Behavior with this feature: User initiates a binary file download. A hash is supplied in a 'Digest' header. Once the download completes successfully, Firefox automatically uses the hash to validate the file. If there is an error during transfer, a retry option can be given. If the file is complete and without errors, it can be shown as a typical completed download.

    Marcos used Firefox up until version 3 when he decided to switch to Chrome. He's been using Chrome for a couple of years now but heard that Firefox 4 was blazing fast and had some great new features. He downloads Firefox but when he launches it, it has his three year old Facebook and Bank of America passwords stored which don't work any more. It's also missing all his new favorite websites and what's even worse than that is the awful Ask toolbar that just showed up in Firefox one day back in 2008. He decides Firefox still sucks and goes back to Chrome. Julia was a Firefox 4 that decided to Give IE 9 a try and found she loved it. Since moving to IE 9, she's amassed about 1500 new favorites and a bunch of new logins. Hearing that Firefox 6 is the bomb, she downloads it. When starting Firefox for the first time, it asks her if she'd like to migrate her IE 9 settings and data. She says yes and Firefox does. She has no more reason to go back to IE 9 and so she makes Firefox 6 her new default.

    Mark gets a tip from a friend about, a place to review and share your favorite salad bars. Mark visits the site and is eager to contribute his own reviews as well as connecting with friends to find out which salad bars they like. Mark sees a "sign in" button on the SaladFans site, and when he clicks on it a Mozilla ID pop-up dialog comes up telling him that the site is asking for a verified email address to sign-in. Mark hasn't used Mozilla ID before, so he clicks the "register" button. Mark now types in his email address, and chooses a password for his account. After he's done, Mozilla ID tells him that a verification message has been sent to his email, and he needs to click on a link there before proceeding. Mark checks his email and clicks on the link in the message Mozilla ID sent him. The link opens up a new pop-up replacing the previous one, which welcomes him to Mozilla ID and asks him if it's OK to disclose the email address to Mark clicks OK, the dialog closes, reloads, and Mark is now signed into!

  • Security/Features/Intranet CSRF Blocker  + (RFC 1918 defines the set of CIDR blocks wh
    RFC 1918 defines the set of CIDR blocks which are not publicly addressable from the Internet and which are generally used to address hosts found on private home or enterprise networks. Included in this range are:,, and Starting around 2006, security researchers, notably Jeremiah Grossman and Robert Hansen, began pointing out an architectural weakness in the Web that allowed (untrusted) websites on the public Internet to cause requests to be sent to hosts on these private networks, which would otherwise be protected by NAT. Malicious requests of this type can be used by an attacker for: port scanning internal networks, reconfiguring home routers, sending print jobs to network printers, and CSRF to applications that use network access as authentication.

  • Silent Update not now prompt  + (Sandra is using Firefox to check her email
    Sandra is using Firefox to check her email and at the same time in the background, Firefox is being updated to the latest version. However, as Firefox runs through the installation process it also checks for add-ons compatibility and identifies two add-ons that are unsupported with the new version of Firefox. Given there are incompatible add-ons, Firefox will not update Sandra to the latest version of Firefox and enter a 10 day grace period that will continue to check in the background if her incompatible add-ons become compatible. There are a few things to note here: *If both add-ons become supported within the 10 day grace period and the Firefox update happens in the background successfully, Sandra will be able to continue to user Firefox as if nothing happened. *Sandra continues to have at least 1 incompatible add-on on the final day of the grace period and Firefox will prompt her to update at that point with some language "warning" language that her browser is not secure and she could be vulnerable to attacks. She has the option to "remind me later". *If she selects "remind me later", Firefox will defer for 10 additional days and on day 20, Firefox will automatically update her to the latest version and disable any add-ons that continued to be incompatible. Firefox informs her via the notification bar that certain add-ons were disabled due to a Firefox security update. Things to note here -- the reason to go down the path of a "required" update is the following: *Based on our data, we have learned over time that 99% of active add-on developers update their add-ons to become compatible with the latest version of Firefox. *To reduce product fragmentation and user confusion, our goal is to offer the most secure, feature-rich and optimized browsing experience that continues to move the web forward. All Firefox users should be offered that opportunity and we're fully aware that certain add-on functionality is critical to users' workflow and will do our best to work with developers to stay updated. *Users will continue to have the option to turn off 'Updates' in general, but are encouraged to leave that checked so they have the best experience. Not only will we continue to innovate by delivering new features, but enhancements under the hood like memory reduction/performance/etc. will help create new experiences across the web.
